Advances in AMC: A Review of Processing Techniques, Mechanical Performance and Wear Properties

International Journal of Innovations in Science Engineering and Management., Journal Year: 2025, Volume and Issue: unknown, P. 256 - 261

Published: March 19, 2025

The global utilisation of Al alloy has been significantly increased, and the manufacturing "aluminium matrix composites (AMCs)" a significant source revenue employment, as result inclusion variety reinforcements to Al. This article provides comprehensive survey diverse literature that conducted on progress (AMCs)". review concluded advancements in graphene-reinforced AMCs have enhanced mechanical tribological properties. Powder metallurgy (PM), particularly SPS process, proves effective achieving superior densification minimizing undesirable phases. Composite performance is by strengthening processes such "CTE mismatch, Hall–Petch, Orowan, load transfer". Reinforcements like SiC, carbon-based materials refine grains, enhancing “tensile strength, hardness, wear resistance”. use nano-reinforcements ensures better structural integrity, while self-lubricating elements improve Additionally, sustainable natural minerals offer economic environmental benefits. Optimal processing conditions, including controlled atmosphere stirring time, are crucial for uniformity properties AMCs.

Current-Carrying Wear Behavior of the Laser-Alloyed Al/W Composite Layer Under Different Currents

Micromachines, Journal Year: 2025, Volume and Issue: 16(5), P. 523 - 523

Published: April 29, 2025

The Al/W composite layer was fabricated on the surface of aluminum alloy using laser alloying technology to enhance current-carrying wear resistance. Additionally, behaviors and substrate were investigated under different currents. results indicate that presence hard phases such as W Al4W in significantly enhanced resistance material. Specifically, average friction coefficient currents reduced by approximately 9.3–35.8% compared substrate, rate conditions decreased about 1.9–6.0 times. For adhesive is dominant mechanism ranging from 0 60 A. However, current increased 80 A, severity arc erosion intensified, transitioned a combination wear. In contrast, for layer, abrasive absence electrical current. Upon introduction current, changed coupling effect

Investigations on Microstructure, Mechanical, and Wear Properties, with Strengthening Mechanisms of Al6061-CuO Composites

Journal of Manufacturing and Materials Processing, Journal Year: 2024, Volume and Issue: 8(6), P. 245 - 245

Published: Nov. 5, 2024

Metal matrix composites (MMCs) reinforced with Copper Oxide (CuO) and Aluminum (Al) 6061 (Al6061) alloys are being studied to determine their mechanical, physical, dry sliding wear properties. The liquid metallurgical stir casting method ultrasonication was employed for fabricating Al6061-CuO microparticle-reinforced composite specimens by incorporating 2–6 weight percent (wt.%) CuO particles into the matrix. Physical, properties were investigated in MMCs, adopting ASTM standards. experimental results show that adding an Al6061 alloy increases its density 7.54%, hardness 45.78%, tensile strength 35.02%, reducing percentage elongation 40.03%. Dry measurements on a pin-on-disc apparatus MMCs outperform resistance. MMCs’ has been predicted using many strengthening mechanism models elastic modulus through several models. of is predominantly influenced thermal mismatch, more so than Hall–Petch, Orowan strengthening, load transfer mechanisms. As content increases, effects due dislocation interactions between reinforcement particles, coefficient expansion (CTE) difference, grain refinement, consistently improve. also examined optical microscope (OM), energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD), scanning electron microscopy (SEM) before after fracture tests. investigation shows material increased showed higher mechanical tribological characteristics.
